Abstract

A catheter assembly for an intravascular ultrasound system includes a catheter and an imaging core. The catheter includes a lumen extending along the longitudinal length of the catheter from the proximal end to the distal end and the imaging core is configured and arranged for inserting into the lumen. The imaging core includes a rotatable driveshaft, at least one transducer mounted to the distal end of the rotatable driveshaft, and a twisted wire cable coupled to the at least one transducer. In addition, a number of different transducer arrangements and methods of making transducers are presented.
